A man who spent more than a decade in prison for second-degree murder was one of the three people recently elected to a school board in Colorado.

Thomas Seaba was released from a North Carolina prison in 2010 after serving over 11 years for the death of a fellow Marine.

"It was obviously a set of horrific mistakes compounding on one another, which led to me serving time in prison," Seaba told KKTV about the 1997 murder.

Col. Donnie Worrell told the outlet that Seaba shot the victim in the back of the head, and then later returned to shoot the man four more times. Seaba said he was initially arrested on first-degree murder, but pleaded guilty to a lesser charge.
